摘　　要：在形态学研究和分子系统发育分析的基础上,本研究报道了采集自海南省的环纹炭团菌属3个中国新记录种,分别为白色环纹炭团菌(Annulohypoxylon albidiscum)、班帕登环纹炭团菌(A. bahnphadengense)和斯普格环纹炭团菌(A. spougei)。根据国内采集标本材料,文中提供了3个新记录种形态特征描述和图示。基于ITS序列采用最大似然法和贝叶斯法构建系统发育树,3个种均得到分子数据的支持。此外,将每种都与模式标本的特征进行比较,并讨论与相似物种的鉴别特征。研究标本现存放于中国热带农业科学院热带生物技术研究所大型真菌标本馆(FCATAS)。Three newly recorded species of China,viz.Annulohypoxylon albidiscum,A.bahnphadengense,and A.spougei,are described and illustrated based on the morphological characters and molecular phylogeny.The specimens were collected from Hainan,China.The detailed morphological features descriptions and photographs were provided for each species.Maximum likelihood analysis and Bayesian inference were used to construct phylogeny trees based on ITS sequences.The three species were supported and confirmed by molecular data.The comparisons between the three Chinese records and holotype specimens were discussed.The specimens are deposited in the Fungarium of Chinese Academy of Tropical Agricultural Sciences(FCATAS).
